strawberries

Strawberries are always a popular plant for the home garden because they are delicious and easy to grow in our Pacific Northwest climate. Plus, they can be grown easily in small spaces and in containers. This information sheet provides you with basic advice on planting, care and pruning.

Choosing YOUR Plants

Choose your varieties according to harvest time, location, and use. Within each class of strawberries below there are multiple varieties with varying sizes and flavors. For more detailed information on any specific variety, please refer to individual plant signs or consult one of our nursery professionals.

There are 3 classes of Strawberries:• JUNE-BEARING (summerbearing) varieties produce one large crop in June.• DAY-NEUTRAL varieties fruit continuously throughout the summer and into fall.• EVERBEARING (two-cropping) varieties produce one crop in June and another in early fall.

Where will you be planting your strawberries?

DAY-NEUTRAL and EVERBEARING strawberries produce few runners, making them ideal if you would like your plants to remain somewhat neatly in their areas. They are great for borders, garden beds, and hanging planters. If you have a large space or would like your strawberries to spread more rapidly, choose JUNE-BEARING types.

Note: Strawberries are self-fertile so only one variety is necessary for successful yields.

Soil & PLANT Preparation

Choose a location with well-drained soil that receives full sun. Prepare the site by incorporating new organic matter using a planting amendment such as compost or soil-building conditioner. The goal is to have soil that is composed of about 25% new organic matter and 75% existing soil. You can add an all-purpose or small-fruit fertilizer at planting time, following the directions on the package.

When planting in containers, always choose a high-quality potting soil. Containers filled with garden soil will not drain well and the soil will be too heavy for your strawberry plants' liking.

Prepare strawberry plants by removing them from pots and gently massaging the roots to separate them slightly, then plant.

NOTE: Bare-root plants should be soaked in water for about an hour before planting them so the crown remains just above the soil (crowns planted below the soil are subject to fungal disease).

Planting IN THE GARDEN

There are two highly successful planting systems to choose from.• The Hill System• The Matted Row System

The HILL SYSTEM generally is the best system for DAY-NEUTRAL and EVERBEARING strawberries because they produce relatively few runners. After preparing the soil, make mounded rows about 6-9 inches tall and 1-2 feet apart. Plant the strawberry starts 12-15 inches apart in the top of the mounded rows. Maintenance consists of simply removing all the runners that grow between the rows before they root. The idea is that by removing the “baby” plants (runners) the mother plant can focus on making bigger and better fruit.

The MATTED ROW SYSTEM is generally best for JUNE-BEARING strawberries because they produce ample runners. Plant the strawberry starts 1 foot apart in rows 3-4 feet apart. Then allow many of the runners to spread and fill in the rows. Don’t let the runners grow in too densely. The plants need as much sun and air in contact with the foliage as possible. Pruning out excess runners and foliage will likely be necessary.

planting in containers

Strawberry plants do very well in all types of containers: plastic, wood, ceramic, or terra cotta. Whichever container you choose, be sure it has drainage holes. Strawberries do not like wet feet.

Simply fill the container with high-quality potting soil and an all-purpose or small-fruit fertilizer, following package directions. Plant one strawberry plant for every 10-12 inches of pot diameter. Strawberries have a spreading habit and shallow roots, so an extremely deep container is not necessary, but choose containers at least 6-8 inches tall. If you prefer a fuller look in your container right away, plant more densely but divide the plants after one year so they don't become overcrowded and underperform.

Strawberry care

WATER deeply and thoroughly on a regular schedule throughout the dry summer months. Drip watering or a soaker hose is preferable to overhead watering and helps avoid fruit molding and other diseases. For containers, water when the surface of the soil begins to dry out. Strawberries definitely don't like sitting in wet, soggy soil but don't want to dry out either!

FERTILIZE when planting and then annually in April with an all-purpose or small-fruit fertilizer, following the directions on the package.

REPLANT with new strawberry plants after 4-5 years because by then your plants will likely have diminished yields. It’s best to wait for a few years before planting in the same location due to pests and diseases that can build up in the soil. For CONTAINERS, wash the container with a diluted bleach solution and use new soil when replanting to avoid pests and diseases.

And now for the best part! Enjoy your delicious, homegrown strawberries. Once you've grown your own it will be hard to go back to store-bought strawberries ever again!
